Grizzly bear and her cub visit a bear hair trap in Glacier National Park. The bear leaves hair samples snagged on the barbed wire as it enters and exits the site. Both bears vigorously rub in the lure pile which is a pile forest debris that had a liquid scent lure poured on it.

This is two video clips captured at the same site from two different angles. The rub trees are on one side of the trail and the excavated log is on the other side. Bears that rub on one or more of the trees often visit the log as well. The clips show a grizzly bear rubbing on a tree regularly used by bears then investigates and rubs on the decaying log on the opposite side

A wolf feeds on a road-killed elk carcass in the morning. A grizzly bear with two cubs feeds on the carcass in the evening. A grizzly bear will chuff and pop its jaw when it feels threatened. Sometimes it will also charge at the threat, usually veering off or stopping short -- a bluff charge. Early the next morning a grizzly bear with cubs chuffs and bluff charges a wolf.
